Description

Ethylmorphine is a derivative of morphine with analgesic and antitussive effect. It acts by activating the opioid receptors and thus has a direct influence on the CNS system. Ethylmorphine was approved in Europe for the treatment of dry cough (Codethyline, Dionine).

Sample Use Guides

In Vivo Use Guide

The recommended dose in adults is 50 mg of codethyline per day, i.e. 10 tablets (1 tablet contains 5 mg of ethylmorphine hydrochloride) per day over several intakes, at a minimum of 4 hours apart. In children the normal dose is 1 tablet per intake, to be renewed after 6 hours if necessary, without exceeding 4 tablets per day.
